/**
 * CourseGroupIterator provides access to CourseGroups.     CourseGroup provides
 * access to these objects sequentially, one at a time.     The purpose of all
 * Iterators is to to offer a way for OSID methods to return multiple values
 * of a common type and not use an array.  Returning an array may not be
 * appropriate if the number of values returned is large or is fetched
 * remotely.  Iterators do not allow access to values by index, rather you
 * must access values in sequence. Similarly, there is no way to go backwards
 * through the sequence unless you place the values in a data structure, such
 * as an array, that allows for access by index.
